Embodiment approach 2

[0093] Compared with the first embodiment, the second embodiment only adjusts the transplanting time, specifically, the angelica and marigold adopt the intercropping mode, that is, the angelica and the marigold are transplanted into the field at the same time. Seedling cultivation and management of angelica and marigold, implementation effect evaluation index and cultivation specification (row spacing, cultivation density) etc. are consistent with the implementation mode.

[0094] (1) Angelica seedling cultivation and management

[0095]Compared with Embodiment 1, the angelica seedling raising time is advanced 20 days, and management, fertilization, watering, etc. are the same as Embodiment 1.

[0096] (2) Marigold seedling cultivation and management

[0097] Same as Embodiment 1.

[0098] (3) Intercropping and monocropping modes and specifications

[0099] Same as Embodiment 1. But marigold and angelica were transplanted into the field at the same time.

Abstract

A method for controlling Angelica sinensis root-knot nematode by marigold interplanting belongs to the field of controlling damage by plant parasitic nematodes, and particularly relates to a method for controlling Angelica sinensis root-knot nematode by changing the Angelica sinensis cropping system. The method includes the steps: transplanting marigold to two sides of each ridge (having a bed width of 1.7m) with a plant spacing of 30cm twenty days before Angelica sinensis transplanting; and when 20 days are past, transplanting four plants of Angelica sinensis per row of marigold with a plant spacing of 28cm, and allowing each row of Angelica sinensis to be spaced from marigold by 35cm so as to form 2:4 interplanting of marigold and Angelica sinensis (see attached figures). Compared with single culture of Angelica sinensis, the method can be more effective in root-knot nematode control by more than 75% and also has a composite field increasing effect for both Angelica sinensis and marigold, and land utilization rate is increased by 70%.

Description

1. Technical field [0001] The invention relates to the field of plant parasitic nematode disease control, and more specifically, the invention relates to a method for controlling plant root-knot nematodes by changing farming systems. 2. Background technology [0002] Angelica is a perennial alpine herbal medicine of Umbelliferae. It is a large number of commonly used Chinese medicinal materials in my country. It is not only directly used in traditional Chinese medicine formulas in large quantities, but also is an important raw material and traditional export commodity of many Chinese patent medicines. Angelica is mainly produced in the mountainous areas of southeastern Gansu, mainly in Min County, followed by mountainous and hilly areas in Yunnan, Sichuan, Shaanxi, Hubei and other provinces. They are all annual or biennial cultivated medicinal plants, and have been domesticated as annuals in Yunnan. The adult angelica has a plant height of 40-70 cm and likes a shaded environ...
